Computing how quantum states overlap
Quantum many-body systems are things such as atomic nuclei that consist of many tiny particles moving in complex ways. This makes it extremely difficult to predict how the systems behave as the particles interact. To study these systems, researchers.....»»
Microsoft open-sources infamously weird, RAM-hungry MS-DOS 4.00 release

The end of the quantum tunnel: Exact instanton transseries for quantum mechanics
In the quantum world, processes can be separated into two distinct classes. One class, that of the so-called "perturbative" phenomena, is relatively easy to detect, both in an experiment and in a mathematical computation. Examples are plentiful: the.....»»
Unveiling a new quantum frontier: Frequency-domain entanglement
Scientists have introduced a form of quantum entanglement known as frequency-domain photon number-path entanglement. This advance in quantum physics involves an innovative tool called a frequency beam splitter, which has the unique ability to alter t.....»»
High-precision blood glucose level prediction achieved by few-molecule reservoir computing
A collaborative research team from NIMS and Tokyo University of Science has successfully developed an artificial intelligence (AI) device that executes brain-like information processing through few-molecule reservoir computing. This innovation utiliz.....»»

Demonstration of heralded three-photon entanglement on a photonic chip
Photonic quantum computers are computational tools that leverage quantum physics and utilize particles of light (i.e., photons) as units of information processing. These computers could eventually outperform conventional quantum computers in terms of.....»»
Political "color" affects pollution control spending in the US, new study finds
A new study led by the University of East Anglia (UEA) shows how firms in the United States behave differently depending on the political party in charge—even if they do not change policies......»»
Scientists tune the entanglement structure in an array of qubits
Entanglement is a form of correlation between quantum objects, such as particles at the atomic scale. The laws of classical physics cannot explain this uniquely quantum phenomenon, yet it is one of the properties that explain the macroscopic behavior.....»»
